[OpenLayers-Users] Problem with namespace param in vector strategy

[sylvie fiat]

Hi,

I figure out that my problem wasn't from namespace option but from WFS version. I just started using WFS 1.1.0 and my old filters where not working anymore, I think it wasn't diplaying anything because I was using HTTP protocol, so I started using WFS protocol and then it was not using my filter, just displaying every features of the layer.
I found a patch http://trac.openlayers.org/attachment/ticket/2292/patch_ticket2292_r9686_A3.patch which I might not hav correctly integrated to my openLayers 2.8, so I tried the SVN and now it is working! ...But just for my BBOX filter. When I try a featureId filter or a Comparaison.EQUAL_TO filter, I have different issues (I use a fonction to pass filter to my vector layer so it should theoritically have the same behavour)

featureId filter:

filter = new OpenLayers.Filter.FeatureId({
        fids: tstation.ST102
    });

I have in my result <gml:featureMembers/>
 which means nothing... and I am sure my feature exist, not sure the way to call fids behave the same ? Do I still need featureType.featureId ?

Comparaison filter:

filter = new OpenLayers.Filter.Comparison({
        type: OpenLayers.Filter.Comparison.EQUAL_TO,
        property: property,
        value: value
    });

I have a 

 <ows:Exception exceptionCode="NoApplicableCode">
    <ows:ExceptionText>java.lang.RuntimeException: Parsing
      failed for PropertyName:
      java.lang.NullPointerException Parsing failed for
      PropertyName: java.lang.NullPointerException null</ows:ExceptionText>
  </ows:Exception>

but my request do have the 
<ogc:PropertyName>topp:idespece</ogc:PropertyName>

I don't really know what it might be

Thanks again,
Sylvie

Ok I am sorry it was just a problem of copy/paste... I wouldn't have had any answer with that request...

namespace:'xmlns(topp=http://www.openplans.org/topp)',

is my real javascript, as I said I have an answer (with the correct features inside) but cannot managed to have any display on the map. I have tried without style and nothing changed.

Regards,
Sylvie
